SPECIIE'ICATION forming part of Letters Patent No. 319.949, dated June16, 1885.

` Application filed April 20, 1884. (No model.)

To all whom it may concern:

Be it known that I, IsAAo W. BOATMAN, of Seven Mile, Butler county,Ohio, have illvented certain new and useful Inlprovements inSoil-Dressing Machines, of wllich the following is a specification.

This invention relates to a machine forfine-` ly dressing the plowedsoil and fnrrow-marking the same at one passa-ge of the machine.

ro The improvements will 'be clearly understood from the followingdescription, taken in connection with the accompanying drawings,

in which- Figure 1 is a side' view of a machine embodying myimprovements; Fig. 2, a plan of the same with portions broken away, and

Fig. 3 a transverse section upon a comparatively large scale of one ofthe Glitter-teeth.

In the drawings, A represents a supporting main roll or ground-wheel ofthe machine;- B, a boxing over the same; C, an endpiece of the boxingforming the aXle-supports of the roll A; D, a tongue rigidly secured tothe boxing B; E, a double-tree; F, tongue-braces';

Vz 5 G, draft-chains reaching from the ends of the double-tree rearwardto the boxing; H, a post proj ecting upward from the center of theboxing; I, a seat-bar located above the tongue and in line with thetonguev and freely pivoted to the top of the post lH, the axis of thepivot being parallel with the axis of the roll A; J, a driverls seatfitted to slide freely along the bar I; K, a removable stop-pin in therear end of the bar I, serving to prevent the seat sliding clear off thebar; L, a rectangular horizontal frame provided With teeth and pivotedto the roll structure, in front of which it is located; M,connecting-bars frcely pivoted at their rear ends to the roll structure;N, bolts passing through slots in the front ends of bars M, and servingas a means for adjustably securing the bars to the frame L; O, boltsaiding in securng the bars M to the frame L; P, holes at the front endof the sides 4 5 of the frame L corresponding to the rear holes of thebolts N and O; Q, side pieces of the frame L; R, vertically adj ustablegaging- Wheels located near the front of the frame L; S, T, and U, themain bars of the franle L,

lying parallel with the axis of the roll; V, a

series of inclined cutter-teeth secured like harrow-teeth in the bal' S;W, harrow-teeth secured in the bar T and set intermediately withreference to the Glitter-teeth; X, a leveling-scraper secured. to thefront edge of bar U; Y, a pair of furrowing-markel's secured to the barT; Z, pivoted connecting-bars reaching from the front end of bar Idownward to the frame L, being attached at theI frameLto acentrally-located bar identical Wit-h the side pieces, Q.

The roll structure llas its tongue rigldly connected, and 'consequentlythe pull of the team is directly upon this roll structure, the chains Gserving to transmit the side pull in tul'ning and tllus relieving theteam from side pull at the end of the tongue. The frame L becomes pushedalong in front of the roll structure, and it is free to rise and fallindependent of.the roll structure, oscillating upon 7( the-axisof theroll structure where the connecting-bars M are loosely pivoted. Thegaging- 'Wheels Rrun upon the soil and can be'adj usted vertically toregulate the depth of working for the teeth. As the front frame risesand falls, the seat-bar I may oscillate upon its post-pivot. The drivermay shift his seat forward along the bar, so as to cause his weight toeXert a downward pressure 'upon the front frame, or he may shift it tothe rear of the post H, so as 8.; to exert a lifting force to the frontframe, or he may shift it directly over the post H,where his weight hasno effect whatever upon the front frame. The row of cutter-teeth V arebent rearward, so as to present a runner-like inclination at theirfaces, and they are of a triangular section, as shown in Fig. 3,presenting acute cutting-edges. The teeth W are ordinary harrow-teethset to work deeper than the teeth V. The scraper Xlevels the dressedsoil. The furrowing-markers Y are set a proper distance apart to suitthe desired marking, and they project below the scraper. Thedressing-frame,it will be seen,is pushed along in front of the rollstructure, and it is not af- '95 fected Vertically by the draft of theteam. The cutter-teeth cut the larger clods, their inclined facesserving to cause them to cut thrOu/gl/ clods which, were their cuttingfaces Vertical, they would tend to push in front of them. The roo harrowteeth are thus called upon to dispose only of clods of manageable size.The

` roller. .40

scraper levels the dressed soil nicely, leaving neat and sharply-definedmarker-furrows,and

the roll structure gives the dressed soil a final pressing, though theroll structure is not used to act as a land-roller, its purpose beingsimply to form a wheeled structure to which the draft may'be applied andby which the dressingframe may be pushed, and by which the postpivot ofthe lever I may be supported. More bars T with their harrow-teeth may beprovided in the front frame, if desired.` By means of the slot and boltN and the adj ustable Wheels R the front frame may be adjustedVertically with reference to the depth of working. The connecting-bars Zare provided with crossholes,in any one of which a pin maybe placedunder or over the tongue, whereby the entire structure may be deprivedof its articulation, as may be desired, when the front frame is liftedfor leaving the field, or when the front 'frame is to be held firmlydown for dressing peculiar soils. y

When the machine is to be used as a dragharrow, the roll structure goesin front of the frame L, as indicated by the dotted circle a, the bars Mand the seat-bar I being reversible to permit of the change.

A combined roller and harrow has been heretofore devised and patented inwhich the .tongue was pivoted to the roller-axis, and in which severalharrow-bars located in front of the roller were connected by drag-barsto hooks in the tongue in front of them. In this device any Variation inthe height of the neck-yoke altered the line of draft of theharrow-bars. I disclaim such device as of my invention. A device hasalso been contrived and patented in which a harrow is drawn to the rearof the I disclaim such as of my invention.

Another device, also patented, exhibits a draftframe connected by freelinks to a roller placed behind, a harrow-frame located within thedraft-frame'and connected by hinge-like devices, and a tongue pivoted tothe front of the draft-frame. In this device the angle of draft varieswith every Vertical position of the front end of the tongue. I disclaimsuch as of my invention. i

I claim'as my invention- 1. In a soil-dressing machine, the combinationof the rigid-tongued roll structure,a seatbar pivoted with referencethereto, a front frame provided with teeth and articulated to the rollstructure, the gaging-Wheels R, the shifting seat J ,and theconnecting-bars Z,substantially as and for the purpose set forth.

2. The rigidly-tongued roll structure, the soil-dressing frame L,connected theret-o in front by pivoted bars, the front row of inclinedeutter-teeth V, and one or more rows of harrow-teeth,W, and the scraperXto the rear of and for the purpose set forth.

3. The rig'idly-tongued roll structure, the soil-dressing frame L,connected thereto in front by pivoted bars, the front row of inclinedcutter-teeth V, the rear row of harrow-teeth W, the scraper X, and themarkers Y, combined substantially as and for thepurpose set forth.

4. Inasoil-dressing-machine, the roll structure, the reversible bars M,pivoted thereto, and the soil-dressing frame fitted to havesecured-to'its front and rear ends alternatively thev harrow-teeth,combined substantially as said connecting-bars, combined substantiallyas and for the purpose set forth.
